Obs Project
Having recently discovered the Absco pool pump shed observatory concept, I've decided I'm going to go down that path too. Today I started by building a mockup frame to check my setup will fit and I've concluded it is a perfect match.
I'm now trying to decide what to do for the floor. I'm looking for a solution that:
1. Can cope with a lot of rain/runoff so it needs to have a bit of ground clearance
2. Keeps ants out
3. Prevent ground moisture creating humidity in the obs
4. Stable so I'm not having to mess with polar alignment all the time
5. Semi permanent so I can remove/move it if necessary
I had a look around Bunnings today to checkout what was available and noticed Absco also make a produce called smart slab. It is a lightweight precast concrete slab that comes in 1.5x0.78 m sections. I'm considering using two of these and building a treated hardwood sleeper base to sit underneath to create some additional ground clearance. I'd lay some plastic sheeting down first then sleepers than the smart slab system. This would require 2 smart slab pieces with a join down the middle - I'm thinking some flexible exterior silicone to seal the gap between the slabs.
Interested in your views on this solution.
